I tried to contact Shanghai Normal University and the Shenzhen HakkaAssociation, but did not receive any response. But that was two years ago. Maybe their email and structure were not ready yet. I did not have their address. You might be able to do a search on the net to find out. I am out of officeright now until 12/21 and can't help you much. I am forwarding your mail to theHakka forum and maillist. Hopefully some other Hakka fellows can help you.
